Necesitatea tratamentului endodontic apare odata cu imbolnavirea ireversibila a pulpei dentare, respectiv a inflamatiei acesteia datorita microbilor care o invadeaza.
Totusi datorita cantitatii mici a substantei dentare coronare restante in urma tratamentului se recomanda acoprirea cu coroana dentara (studiile actuale arata ca dintii tratati endodontic si neacoperiti cu coroane au o rata de fractura de 65%).
Astfel, dintele va fi izolat complet de mediul oral atat de incarcat microbian (gura are cea mai mare incarcatura microbiana de la nivelul organismului uman), si nu va exista riscul suprainfectarii in timpul lucrului.
Dupa ceasta faza se va incepe lucrul propriu-zis, folosind obligatoriu un mijloc de magnificare de tipul microscopului de operare sau eventual a lupei dentare. Lucrand fara mijloace de magnificare, practic lucram aproape orb.
Pulpa dentara este reprezentata de tesutul moale aflat in interiorul dintelui (canalele dentare), respectiv de vase de sange, nervi si tesut conjuctiv.
In timpul dezvoltarii dentare, aceste structuri sunt raspunzatoare de formarea structurilor dure ale dintelui (smaltul si dentina).
De regula simptomatologia este atenuata prin administrarea de antiinflamatorii (ex: Ibuprofen).
